3 = 3
4 = 2.2
6 = 2.3
KPK = 12
07.05 + 12 mnt = 07.17 (a)
15. 24.000.000 : 30 = 1 : 800.000 (c)
16. Perbandingan baru
A : B = 3 : 5
B : C = 5 : 7
A = 15
B = 25
C = 35
A + C = 50
A + B + C = 75
50/75 = 2/3 x 300.000 = 200.000 (c)
17. 13 + 25 = 38
Maaf klo ada yg salah
15) skala= jarak pada peta/jarak sebenarnya = 30/24.000.000 = 1:8.000.000 (D)
16) Agung:budi = 3 : 5
Budi : citra = 5 : 7
Agung:Budi:citra =15:25:35
jumlah uang Agung&Citra / jumlah uang mereka =(15+35) / (15+25+35) x 300.000
50/75 x 300.000 = 200.000 (c)
17) 169 kuadrat + 5 pangkat 2 = 13+25=38 (C)
